A check dam is a small, sometimes temporary, dam constructed across a swale, drainage ditch, or waterway to counteract erosion by reducing water flow velocity. [1] Check dams themselves are not a type of new technology; rather, they are an ancient technique dating from the second century AD. [ 2 ]
[21]: 19 Bioswale design is intended to safely maximize the time water spends in the swale, which aids the collection and removal of pollutants, silt and debris. Depending on the site topography, the bioswale channel may be straight or meander. Check dams are also commonly added along the bioswale to increase stormwater infiltration. A bioswale ...
A check dam is a small dam designed to reduce flow velocity and control soil erosion. Conversely, a wing dam is a structure that only partly restricts a waterway, creating a faster channel that resists the accumulation of sediment.
A check-dam [...] is built to retain runoff waters [...]. A spillway regulates the level of the water [...] to prevent the destruction of the check-dam.. [4] The embankment height should be 3–4 times the designed water depth, and the outlet should be to the side of the main flow to prevent direct through flow.
An anicut (Originated from Tamil language அணைக்கட்டு - Aṇaikaṭṭu and Kannada language ಆಣೆಕಟ್ಟು - Āṇekaṭṭu) and also in Telugu language as ఆనకట్ట - ÃnaKaṭṭa, is a masonry check dam that is constructed across a stream to impound water for maintaining and regulating irrigation. [1]
A viral TikTok video claims that flooding in North Carolina was caused by the release of water from a dam, not from Hurricane Helene. “Makes since [sic]! How can a town, 2000ft in elevation ...
A detention dam is a dam built to catch surface runoff and stream water flow to regulate the water flow in areas below the dam. [1] Detention dams are commonly used to reduce the damage caused by flooding or to manage the flow rate through a channel. [2] Detention dams can also be constructed to replenish groundwater and trap sediment. [2]
A leaky dam was added to the arsenal of flood prevention tools. [4] This type of structure is what nature uses for similar events. Logs from fallen trees are placed at intervals down the stream acting as a barrier, holding the silt and small debris back and allowing just the water that overflows the structure to continue the course of the ...
